Since the membership numbers are top secret at the NCBA,I have to assume R CALF has taken the lead and is now the largest cattle mans group.I dont think any one will post NCBA member ship numbers,some one might make an educated guess to do a little track covering but no hard numbers.............good luck PS I love this information age,lots harder to decieve the cattle man now.Could this be the reason for R CALF s growth?
